This four part series (originally published on Aggregate’s website) examines the Gherkin, the London office tower designed by Foster + Partners, showing how the urban icon engaged and leveraged perceptions of risk. In part one, author Jonathan Massey introduced the concept of "risk design” to describe how the Gherkin’s design managed the risks posed by climate change, terrorism, and globalization. In part two, Massey examined the building’s treatment of climate risk. In part three, below, he explains how the Gherkin redesigned the risk imaginary associated with terrorism.
Mornings the Zamboni scrubs the plaza. Moving across the pavement in parallel lines connected by tight turns, the sweeper cleans the stone of cigarette butts and spilled food and beer left the night before by the underwriters and bankers who patronize the bar and shops in the building’s perimeter arcade as well as the adjacent restaurant that in fair weather sets up outdoor tables and chairs.
By pulling away from its irregular property lines, the tower achieves almost perfect formal autonomy from its context. The gap between the circular tower base and trapezoidal site boundaries forms a privately owned public space, a civic and commercial amenity in this densely built part of the City.
